To all whom it may concern:

Be it known that I, FRANK J. BALLINTINE, a citizen-of the United States, res iding at Perth Amhoy, in the countyof Middlesex and State of New Jersey, have invented certain new and useful Improvements in Roof Coverings, whereof the following is -a specification, reference being had to the accompanying drawings. This invention relates and more particularly to shin les' of the t pe which are fabricated from ti rous material such as aper, felt, or the like, suitably treated witi substances to render said shingles weather-proof and flexible. An object of the invention is to provide a shingle which is so constructed as to pro vide means to secure the lower or exposed end of each shingle in such a manner as to cause the same to lay and'remain fiat against to roof coverings the roof, thus precluding the entrance of rain v or snow beneath the shingle ends. This is 11000 lished in the present invention by provi ing one or more tongues on one i shingle together with a locking flange so that the tongue of an overlapping shingle may engage the flange of an underlying shingle, thus securing together the shingles of adjoining courses. As a result of the construction employed, to he hereinafter more fully set forth, these shingles are caused to simulate very closely the appearance of Wooden shin ice by reason of t e thickened end of each s iingle.

The above and other objects are accomplished through the preferred embodiments of m invention, illustrated ;a the accompanym drawings in which:

Fig. 18 a View in plain of a fragment of a roof covering consistingof an assemblage of my improved shingles.

Fig. II is a view in perspective of a unit shingle. illustrating more clearly the detail construction.

Fig. Ill is a View in section taken on the line, Ill-III of Fig. I, illustratii'ig the manner in \\'lllCll the shingles are interlocked; and 4 Fig. IV is a View in plan of a fragment of a root covering constructed of strips to facilitate the laying of courses, and illusnting a modified form of my invention.

With reference to Figs. I, II and Ill, 10 indicates an oblong shingle of the Llulltll outline and dimensions, constructed ol' paper,

fiber, or the like, treated with bituminousmaterials to render the saine;fiexible,,nonporous and weather-proof. One end, to-c onstitnte the exposed end of the shingle, is folded over to form a locking flange. 11 and each of the two side edges of the shingle is formed with a slot 12, which slots extend toward each other, diagonally relative to the.

edges of the shingle toward the rear ornnfoldedend. The formation of these slots results in the difinition of tabs 0r spurs 13 wholly within the eripheral confines and directed toward the olded end of the shingle.

These shingles 10 are laid in courses in the.

usual manner and preferably in closely spaced relation as shown in Fig. I, permitt ng one course to overlap the next. and causing each of the flanges 11 of an overlapping course to extend over the adjacent marg ns to two of the shingles 10 of an underlying course so. that their exposed ends present a bond eile'et. The shingles 10 of one course should be laid relative to those 01 the next so that the adjacent tabs or spurs 13 of adjacent shinglps of an underlyin course are seated bet-w en the flange 11 and loody portion of an overlapping shingle of the next course above. As a result the flanged end 11 of the shingle 10 is held down and compelled to lie flat against the root at all times. This arrangement of interlocking members isclearly illustrated in Fig. III.

To -facili'ate the laying of courses these shingles may be fabricated in strips, an expendient frequently adopted. To this on a strip 14 is rovided with spaced, transversely extending slots 15,

said diver ing ends. These tongues 16 are the equiva ent of a pair of tabs or spurs 13 of the first form of shingle when a pair of such shingles are laid in a course. These etri s 14 are laid, one overlapping the other, to efine the coruses of the shingles and to produce a bond effect so that one shingle of an upper course overlaps the adjacent margins of two shingles of a lower course. Each tongue 16 of an underlying course or strip is then introduced between the flange 11 and the body portion of an overlappin shingle of the next course above. It will e noted that in either of these forms the folded ends of the shingles produce a thickened appearanceand a roof covered with such shingles les em'oies very closely p. roof covered with the conventional form of wooden shingles which are relatively thick at their exposed ends and taper toward the other ends. vFurthermore, the ends of the shingles are reinforced by reason of the fold so as to resist flexing and are thus caused to remain flat against wind pressure, thereby precluding the entrance and accuinlulation of rain or snow thereunder.

Having thus described my invention,

claim:

1. A flexible weather-proof oblon shingle having the lower narrower edge f0 ded under to form a flange with the longer opposed side edges angularly' notched to provide downwardly directed locking spurs wholly within the marginal confines thereof, said spurs being adapted to engage between the flange and body portion of an overla ping shingle to hold the flanged end of the atter fiat. v r

2. A covering for buildings embodying rows' of flexible weather-proof oblong shincover 3. As a new article of manufacture, anob-' of the shingle to define spurs wholly 'with-' in the marginal confines thereof and downwardly pointed in divergent relation.

fl. A roof covering comprising strips of flexible weather-proof material, each stri having one longitudinal edge thereof slotted at uniformly spaced intervals to define a series of oblong shingle ends, each said shingle end having its lower edge underfolded to constitute a flange with the inner end of each slot bifurcated to afford a locking spur, whereby said strips when laid in over-lapping relation form a shingle course with the locking spurs of an under-lying course engaged upon the flanges of an overlying course.

5. As a new article of manufacture, a strip of flexible weather-proof material hav ing one longitudinal edge formed with transverse slots to define oblong shingle ends with the lower edges thereof under-folded to provide flanges, andthe inner end of each said slot bifurcated to define a downwardly directed locking spur.

In -testimony whereof, I have hereunto signed my name at Bombay India this third day of March, 1922. y
